What would be the ideal situation to pick Ziggs?

I was talking with some friends today, and the conversation circled around to Ziggs. I asked them "when would you pick Ziggs?" as a theoretical question, and their answer came back as "never". I'm curious if G&B agrees with their reasoning:

#The Competition

- A mage with very strong zone control, decent range poke with his Q+AA combo, high burst damage, a mobility spell, and a "respect my personal space!" ultimate. They reasoned there's nothing you'd want to do as Ziggs that you couldn't do more effectively as Azir. Sure, you might be able to do it from further away, but Azir has the tools to let you feel safer up close and personal with enemies. They came to the consensus that because of all that Azir offers, he's the main reason why Ziggs isn't seen as frequently.

- A fully charged Q pokes further and faster than a Ziggs Q. While Ziggs has the upper hand in mobility, they're comparable in terms of CC. They argued that Varus mid was more desirable because of the defensive item situation, which tries to make Armor items stronger by reducing the attackers attack speed or returning auto attack damage, neither of which Q spammer Varus has to worry about. His ability to help take towers was also a plus.

- Came up briefly, for many of the points that made Varus a good pick.

- Far more burst than Ziggs, and good poke with his E. The differences in range were considered to be minimal due to the bounce factor of Ziggs's Q.

#The Meta

Ziggs fell off hard when the Assassin meta rolled in, and hasn't recovered with the Tank meta either. What kind of meta will it take for Ziggs to be a good pick again? How do you see us getting there?

At this point, I'm wondering if there's a reason beyond love of the character to pick Ziggs at all. Hopefully someone can show me something that was skipped over.
